Gigabyte A520M K V2 Ultra Durable AMD AM4 Socket Motherboard, Micro-ATX, 2x DDR4 Slots, 1x M.2 Socket, GbE LAN, 1x D-Sub / 1x HDMI Port

Gigabyte A520M K V2 Micro-ATX AM4 Motherboard – 2× DDR4, PCIe 3.0 x4 M.2, GbE LAN, HDMI 4K@60 + D-Sub

Summary: The Gigabyte A520M K V2 is a compact micro-ATX motherboard for AMD AM4 CPUs, supporting Ryzen 3000/3000G, 4000G, 5000 and 5000G series processors. It delivers modern essentials for value builds: 2× DDR4 slots (up to 64GB), a PCIe Gen3 x4 M.2 (NVMe) slot for fast SSDs, 4× SATA 6Gb/s (RAID supported), Gigabit LAN, and flexible display outputs including HDMI up to 4K@60 and D-Sub (VGA) for older monitors.

Build a reliable AM4 PC for home, office, or entry-level gaming with the Gigabyte A520M K V2. It’s a smart pick when you want a small, affordable motherboard that still supports fast NVMe storage, plenty of USB, and a full-length PCIe slot for a dedicated graphics card—while also keeping HDMI/VGA available for APU builds and multi-display setups.

Key features

• Socket / chipset: AM4 + AMD A520
• CPU support: Ryzen 5000/5000G, 4000G, 3000/3000G series
• Memory: 2× DDR4 DIMM, dual-channel, up to 64GB; supports XMP and high OC speeds (up to DDR4 5100 OC listed)
• Expansion: 1× PCIe 3.0 x16 + 1× PCIe 3.0 x1
• Storage: 1× M.2 (Socket 3, M-Key, 2280) with PCIe 3.0 x4/x2 NVMe + SATA support, plus 4× SATA 6Gb/s (RAID 0/1/10)
• Networking: Realtek Gigabit LAN
• Audio: Realtek HD audio (supports multi-channel output)

Rear I/O 

• Video outputs: 1× HDMI (up to 4096×2160 @ 60Hz), 1× D-Sub (up to 1920×1200 @ 60Hz)
• USB: 4× USB 3.2 Gen1 + 2× USB 2.0
• Other: RJ-45 LAN, 3× audio jacks, PS/2 combo port

Build notes 

• HDMI/D-Sub work only with an APU: the motherboard’s display ports require a Ryzen “G-Series” CPU with integrated graphics. If you use a standard Ryzen CPU without iGPU, you’ll need a graphics card.
• No built-in Wi-Fi: add a PCIe Wi-Fi card or USB adapter if you need wireless.
• Micro-ATX size: ideal for compact cases while still supporting full-size GPUs (case clearance permitting).

Great for: budget AM4 gaming builds, home/office PCs, upgrades from older AM4 boards, or APU builds needing HDMI + VGA support.
